BLOWER AND SHOWER FOB PAPER-MACHINES.

Specification of Letters Patent.

Patented Mar. 5, 1912.

To all whom it may concern:

Be it known that we, OTTO BAKER and EUGENE J. MCGARTY, citizens of the United States, said BAKER residing at Piermont, Rockland county, State of New York, said MCOARTY residing in Clinton, in the county of WVorcester and State of Massachusetts, have invented a new and useful Blower and Shower for Paper-Machines, of which the following is a specification.

This invention relates to a combination shower and blower for spraying water on the gauze cylinders of paper machlnes and for blowing from the gauze any sediment which accumulates.

The principal objects of the present 1nvention are to provide an improved form of shower so arranged that the shower nozzles can be shifted back and forth very readily and kept in proper relation to the blower holes; to provide a simple and convenient arrangement for cleaning sediment away from the shower openings; and to provide means whereby when the latter device is operated the sediment will be allowed to escape from the shower pipe into a waste pipe at the end.

The invention also involves other features as will appear hereinafter.

Reference is to be had to the accompanying drawings in which Figure 1 is a bottom plan view partially in central horizontal section showing a preferred form of the invention; Fig. 2 is a transverse sectional view on the line 22 of Fig. 1; and Fig. 3 is an enlarged sectional view of a portion thereof.

The shower pipe 10 and blower pipe 11 are arranged substantially in their usual relations to each other, being mounted on brackets 12 which support both of them. These brackets preferably are mounted on the machine in a well-known manner which is not illustrated. The pipes are held on the brackets by set screws 13 and the brackets are held in position by screws 14.

The shower pipe 10 receives its supply from a pipe 15 and is provided with a waste pipe 16 at the other end. Along one surface it has staggered rows of shower holes 17 so as to give a continuous spray on all parts of the cylinder. Through a stuffing box or the like 18 extends a rod 19 which is operated by a crank or other handle 20. This rod is provided with a series of disks 21 pinned on the rod or otherwise secured to it. These disks are shown as sectorshaped and extending about two-thirds around the circumference of the shower pipe. They are provided with perforations 22 so as to allow the water to flow through and keep up an even pressure throughout the length of the pipe. The object of the disks is to clean the shower holes 17 through which the water is sprayed on the cylinder. These disks are arranged to clean any accumulated sediment in the pipe which would tend to clog up these small shower-holes. When the sediment requires removing the rod is turned half-way around the pipe and then drawn forward and back with the disks passing over the surface of the pipe adjacent to the holes so as to scrape the sediment therefrom. On the rod 19 is mounted an adjustable collar 24 adapted to come up against a stop 25 and regulate the extent of the movement of the disks. On the other end of this rod is a valve 23 which fits in a valve seat 26 on an elbow at that end. This is arranged in this way so that when the rod is drawn back and forth this valve will open and let the sediment escape during the cleaning operation. Of course it remains closed at all other times.

The blower is arranged in a partially cylindrical guide 30 supported by the bracket-s 12 so that the blower itself can be moved back and forth so as to bring the nozzles 31 into position to operate on various parts of the gauze. This is provided for by using a flexible inlet hose 32. The nozzles preferably are arranged in pairs and are made of round pipe flattened down at the end so as to throw a broad spray of steam at an angle on the gauze. This carries the sediment down so as to prevent it from blowing up on the cylinder and injuring the paper. These nozzles of course or their fittings pass through the longitudinal slit in the guide pipe 30. The pipe 11 is operated by a' lever or handle 33 screw-threaded into the end of a valve casing 34 on the end of the pipe 30. The valve is operated alsoby the handle 33. It will be seen therefore that by this arrangement the blower pipe can be moved back and forth very rapidly without any danger of its getting out of proper position, and that the operator does not have to use care in adjusting it back after having moved it. The form of the blower nozzle is also an improvement.

The cleaning device for the shower pipe. is an important advance in the art as will be obvious from the description which has been given.

Although we have illustrated and described a preferred embodiment of the invention, we are aware that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore we do not wish to be limited to all the details of construction herein shown and described, but

That we do claim is 1. In a paper machine, the combination of a set of brackets each having a pair of passages therethrough, a blower pipe and a shower pipe guide both held in said passages parallel with each other, a shower pipe longitudinally adjustable in said guides, and nozzles from the blower pipe extending on an upward inclination under the shower pipe and terminating near the outer side thereof.

2. The combination with a shower pipe having discharge openings along one side thereof, of a rod running through the same and having cleaning devices thereon for dislodging sediment from around said openings, a waste pipe, and a valve connected with said rod for permitting water to discharge into the waste pipe when said cleaning device is operated.

3. As an article of manufacture, a. shower pipe having staggered rows of openings along one side for discharging water, a waste pipe at the end thereof, a valve for controlling the admission of water from the shower pipe to the waste pipe, and means for simultaneously opening said valve and cleaning the sediment away from said openm s.

Z. As an article of manufacture, a shower pipe having discharge openings in the wall thereof and provided with a central rod running through the same having cleaning devices t-hereon for said openings of a diskshaped form but taking up only a portion of a complete circle, said rod being adapted to be turned on its axis to bring said disks on the side of the shower pipe opposite said openings, said rod having a waste valve on one end and a stop near'the other end for limiting its longitudinal motion.

5. As an article of manufacture, a shower pipe having discharge openings in the wall thereof and provided with a central rod running through the same having cleaning devices thereon of a disk-shaped form but taking up only a portion of a complete circle, said rod being adapted to be turned on its axis to bring said disks on the side of the shower pipe opposite said openings.

6. As an article of manufacture, a shower pipe for paper machines having sector shaped cleaning disks therein adapted to be turned on their axes and to be moved longitudinally of the pipe.

In testimony whereof we have hereunto set our hands, in the presence of the sub scribing Witnesses.
